Select the correct answer. Consider the formula for the slope between two coordinate points, m, shown below. m = y 2 − y 1 x 2 − x 1 Which of the following equations is equivalent to the slope formula? A. y 2 = m ( x 2 − x 1 ) + y 1 B. x 1 = m ( y 2 − y 1 ) + x 2 C. x 2 = m ( y 2 − y 1 ) + x 1 D. y 1 = m ( x 2 − x 1 ) + y 2
The equation that is equivalent to the slope formula is y₂ = m(x₂ - x₁) + y₁
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope between two points A(x₁, y₁) and B(x₂, y₂) is:
Slope (m) = (y₂ - y₁) / (x₂ - x₁)
m = (y₂ - y₁) / (x₂ - x₁)
m(x₂ - x₁) = y₂ - y₁
y₂ = m(x₂ - x₁) + y₁
The equation that is equivalent to the slope formula is y₂ = m(x₂ - x₁) + y₁

At a baseball game, 35% of people attending were supporting the home team, while 65% were supporting the visiting team. If 735 people attending the game supported the home team, what was the total number of people attending the game?
Answer:
1300
Step-by-step explanation:
455 divided by 35%
= 455 x 100/35
= 455 x 20/7
= 65 x 20
= 1300
The total number of people attending the game is 2100.
Given that, at a baseball game, 35% of people attending were supporting the home team, while 65% were supporting the visiting team.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the total number of people attending the game be x.
Given, 735 people attending the game supported the home team.
Now, 35% of x=735
⇒ 35/100 × x=735
⇒ 35x=73500
⇒ x=73500/35
⇒ x=2100
Therefore, the total number of people attending the game is 2100.

Let f(x)=3 x²-4 and g(x)=x-2 . Calculate (f ⁰ g⁻¹)(x) for x=-3 .
If the inverse of f exists, it is represented by f⁻¹ and exists only if f is a bijective function.
If x = -3 then (f ⁰ g⁻¹)(x) is 23.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.
Let the two functions be f(x) = 3x² - 4 and g(x) = x - 2
(g⁻¹)(x) = 1 - 2
(g⁻¹)(x) = -1
substitute (g⁻¹)(x) value in (f ⁰ g⁻¹)(x)
(f ⁰ g⁻¹)(x) = (f ⁰ ) (-1)
then f(x) equation is 3 x² - 4 substitute -1 in x
f(-1) = 3(-1)² - 4
f(-1) = -1
Now when x = -3 the (f ⁰ g⁻¹)(x) value is
f(-3) = 3(-3)² - 4
f(-3) = 23
Therefore, the value of (f ⁰ g⁻¹)(x) for x = -3 is 23.

A florist buys a dozen roses for $12.96 and sells them for $48.48. Find the amount of markup on a single rose.
The amount of markup on a single rose is $2.96
What is profit?Profit = Selling Price – Cost Price.
We have,
We can consider the cost price as:
Bought amount = $12.96
We can consider the selling price as:
Selling amount = $48.48
Now,
Markup price can be considered as the profit:
Profit = Sellin price - Cost price
Profit = $48.48 - $12.96
Profit = $35.52
Since in a dozen we have 12 roses the markup price for each rose is:
= $35.52 / 12
= $2.96
Thus the amount of markup on a single rose is $2.96

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The most of the time, size comparisons between two numbers on the number line are to be made. Different types of inequalities are represented by a variety of notations, including: The symbol a b indicates that an is smaller than b. When a > b is used, it indicates that an is bigger than b. A is not equivalent to b in any scenario. Since a is apparently less than or solely greater than b, these relationships are known as stringent inequalities. Equivalence is not considered.

Rebecca has twice as much money as Rachel. If Rebecca gives Rachel $60, then the two of them will have the same amount of money. How much money did Rebecca have originally?
A.
B.
C.
D.
E.
Answer:
Rebecca originally had 240 dollars.
Step-by-step explanation:
Let's set B as Rebecca's money and C as Rachel's.
Rebecca has twice as much money as Rachel
B = 2C
If Rebecca gives Rachel $60, then the two of them will have the same amount of money
B - $60 = C + $60
let's combine the 2 by subtracting the second from the first
B - (B - $60) = 2C - (C + $60)
$60 = C - $60
$120 = C
so Rachel had 120 dollars.
Rebecca had twice as much, so 240 dollars.
If Rebecca gives $60 to Rachel, they have $180 each. Everything checks out.

The direct variation equation can be used to find other combinations of x and y is y² = 4x³/27
What is direct variation?Direct variation is variation in which one quantity increases as another quantity increases or decreases as anothe rquantity decreases.
How to find equation can be used to find other combinations of x and y?Since we have that the square of y varies directly as the cube of x.
Writing this as a direct variation mathematically, we have
y² ∝ x³
So, the direct variation equation is
⇒ y² = kx³ where k = constant of proportionality
Now, given that when x = 4, y = 2.
Substituting the values of x and y into the equation, we have
y² = kx³
2² = k(3)³
4 = k(27)
k = 4/27
Substituting the value of k into the expression, we have
y² = kx³
y² = 4x³/27

As per the question statement, we are provided with an expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex].
We are supposed to simplify the above mentioned expression.
To solve this question, let us simplify the expression, part by part, i.e., first, let us consider the numerator part which is
[2x² + 3x³ - 3x² -3x -4x - 3].
Here, it is clearly visible that the numerator expression consists of terms having same same variable but with different coefficients, such as
[2x², -(3x²)] and [-(3x), -(4x)]. Therefore, we can perform the mentioned operations on the like terms and thus simplify our numerator.
[tex][2x^{2} +(-3x^{2} )]=(2x^{2} -3x^{2} )=-(x^{2})\\[/tex]
And, [tex][(-3x) + (-4x)]=-(3x+4x)=-x(3+4)=-(7x)[/tex].
Hence, [tex](2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(2x^{2} -3x^{2})-(3x+4x)-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(-x^{2} )-7x-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=(+3x^{3}-x^{2}-7x-3)\\[/tex]
And our denominator is (x - 2). Since, [2x² + 3x³ - 3x² -3x -4x - 3] does not equate to Zero for (x = 2), there (x - 2) is not a factor of the numerator, i.e., the numerator cannot be exactly divided by the denominator.
Therefore, the simplest form of our expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex] is [tex]\frac{3x^{3}-x^{2} -7x-3 }{(x-2)}[/tex].
